This link may be of some help to you. Especially the section headed Change my firmware to WW or Change my Recovery to WW

Read it all through first though to understand what you may need to do.

Thank you so much, i can not believe that i flashed my phone to the WW version and got all the updates and can now uninstall things i don't want and apps dont keep asking for permission, you made it so easy your an absolute star


Hi @kittykat48

For a self confessed 'not that technical' person I'm glad that you weren't intimidated by the 'flashing' procedure and decided, as we say 'Down Under', to 'give it a go'. (translation = will attempt to do this)

Well done! Enjoy your phone.
